Creekos: The Card Game is a trick-taking card game with a customized deck that pits two partnerships of two players against one another, first in an auction to determine the power of their cards, then in the card play itself. At the start of the game two auctions take place, one for the number scale – that is, which value on the cards they hold will be used by the partnership – and a second for the trump color. After this, the players then compete in a trick-taking game that uses customized cards in different categories that relate to one another; in the packet "Hercules' Labors", for example, the categories are Events, Gods, People, Creatures, Lifeless. For each trick, players lay one card in the center of the table – with some cards having special abilities that activate thunderbolts or block other cards – and the most powerful card wins the trick. Once all the tricks are finished, players tally their points (subtracting however many points they bid at the start of the game), and the partnership with the high score wins. Creekos: The Card Game can also be played by only two players, with each player competing on her own.
